The cause is Jira that connects to itself, and if you have a proxy installed, the SSL certificate must be well configured in the Java environment


The Atlassian solution is:

And our proposed solution is:

  • Export the SSL certificate and import it in the Jira JRE security CA cert file (and in the system Java security CA cert file)
  • The proxy MUST be configured to redirect to the url (not to localhost)
  • openssl s_client -connect < /dev/null | sed -ne ‘/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p’ > public.crt
  • keytool -import -alias -keystore /etc/pki/java/cacerts -file public.crt
  • keytool -import -alias -keystore /opt/atlassian/jira/jre/lib/security/cacerts -file public.crt


Thanks to Riccardo for this solution!
